Pronounsebe, sobě, ... is referring thesubject of the sentence. It is obvious, that this pronoun does not exist in the nominative.
example: Pišu sebe do knigy. = I write myself in a book. Pišemo sebe do knigy. = We write ourselves in a book.

There is no need to add personal pronouns (ja, ty, on, ona, ono, my, vy, oni) to verbs. In English,we need to say pronoun in order to express the personal form of the verb, but Slavic verbs themselves carrythis information through the personal postfixes. This style isalso known from Romancelanguages.

Please rememberthatpronounskto? = "who?", čto?= "what?" are used at the positionof the noun, and pronounsktory? = "who?, which?", kaky? (or jaky?) = "what?, what kind of?" are used at the positionof the adjective. But semantically there is no difference between kto? and ktory? and between čto? and kaky?Examples:

Kto jest doma? = Who is at home? (kto = subject of the sentence in nominative, at the position of a noun)

Čto tu dělaješ? = What are you doing here? (čto = object of the sentence in accusative, at position of a noun)

Ktory student tamo sedi? = Which student is sitting there? (ktory = "which" is added to the noun student as its adjective)

Kako jest ime tvojego prijatelja? = What is the name of your friend? (kaky = "what, what kind of" is added to the noun prijatel as its adjective)

Remember, that kto is declined using the animate (A = G) hard pattern, čto is declined using the inanimate (A = N) soft pattern. They have only one form for all three genders:

interrogative pronoun koj = who
Interrogative pronoun koj, koja, koje = which is identical to the pronoun ktory, ktora, ktoro (e.g. is used at the positionof the adjective). This pronoun is inflected in the same way as the possessive pronous moj and tvoj = "my" by the soft pattern.

Remember that the pronoun koj, koja, koje is frequently used in the southern Slavic languages, but the identical pronoun ktory, ktora, ktoro is more used in the western and eastern Slavic languages. These pronouns (e.g. koj, ... and ktory, ...) are inflected in all three genders and all cases as adjectives.

It is possible to create several pronouns using prefixes to the interrogative pronouns. Learn them from this table. The same prefixes (e.g. t-, in-, ni-, ně-, vse-, ...) are used at numerals and adverbs as well.

kaky?

which?

taky

this, such a

ovaky

this, such a (roughly)

onaky

this, such a (distantly)

inaky

other one

nikaky

nobody

někaky

somebody, anybody

vsekaky

everybody, whoever

relative pronouns in subordinate clauses

There are two ways how to refer something from the superordinate clause to the subordinate clause:

Using any standard interrogative pronoun (e.g. ktory, kaky, ...). This methodis chosenina situation where asubordinate clause adds orclarifies some still not fully known concept from a mainsentence.

Example:

Kto jest tamtoj člověk, ktory imaje zeleno auto? = Who is that man, who has a green car? (Here we need to define this unknown man.)Ne hoču auto, v ktorom jest slaby motor. = I do not want a car,in which theengineis weak. (Here we need to define this unknown car.)Ne hoču auto, v kojem jest slaby motor. = I do not want a car,in which theengineis weak. (Here we need to define this unknown car.)

Using special relative pronoun iže. This methodis chosenina situation where asubordinate clauseaddsa new featureto some alreadyknownconceptfroma mainsentence.

Example:

Otče naš, iže jesi na nebesah. = Our Father (V), who are in heaven. (Here we add the new feature to the already known Father.)

The relative pronoun iže has the form iže in all (m., f., n., pl.) nominatives, and in all other cases it has the same forms as the pronoun on, ona, ono, oni with added postfix -že.
